| 摘要 |
The present invention relates to a method for determining at least one parameter related to a patient's spontaneous attempts at inspiration and/or the patient's respiratory effort in attempts at spontaneous inspiration. This can be achieved by determining a pressure gradient ( DELTA P/tm) in relation to a known apparatus pressure (8) and time (tm), said pressure gradient ( DELTA P/tm) being generated by the patient at inspiration, determining a residual positive pressure (4) in the patient's lungs (Auto-PEEP) and generating an output signal. In principle, the output signal can consist of the determined parameters as well as other related calculated results. For example, the pressure gradient ( DELTA P/tm) can be extrapolated against residual positive pressure (4), and both a delay for respiratory assistance and true inspiratory effort can be determined. The invention also relates to a breathing apparatus with which the methods can suitably be performed. <IMAGE> |
